摘要

The invention relates to an extendable clasp (10; 100; 200; 300) with folding buckle for a bracelet, comprising: a support (12; 112; 212) comprising two longitudinal edges (14a, 14b; 114a, 114b; 214a, 214b); at least one flexible blade (17; 170; 270) integral with the support, the flexible blade comprising at least one end portion; at least one pivoting blade (20a, 20b; 120a, 120b; 220; 320) comprising a proximal portion that is articulated at one end of the support by means of a rod (21a, 21b; 121a, 121b; 221) and a distal portion configured to be connected to one of the strands of a bracelet. The clasp (10; 100; 200; 300) further comprises an indexing mechanism for making the bracelet comfortable, arranged to be able to move the rod (21a, 21b; 121a, 121b; 221) relative to the support (12) or relative to the at least one pivoting blade (121a, 121b) in order to position the rod in one indexed position from at least two indexed positions. The flexible blade is arranged in order, on the one hand, to exert a force on the at least one pivoting blade in order to press the pivoting blade against the support (12; 112; 212) in order to hold the clasp in a closed configuration and, on the other hand, in order to lock the rod (21a, 21b; 121a, 121b; 221) in said indexed position.
